What is the meaning of the net worth of a person? For example,
- How do I find out my net worth?
- Bill Gates's net worth is $86.0 billion. Does that mean Bill Gates can give/donate $86.0 billion to anyone tomorrow?
An individual's net worth is the value of the person's assets minus his debt.
To find your net worth, add up the value of everything that you own: your house, your cars, your bank accounts, your retirement investments, etc. Then subtract all of your debt: mortgage, student loans, credit card debt, car loans, etc. If you sold everything you own and paid off all your debts, you would be left with your net worth.
If Bill Gates' net worth is $86 Billion, he likely does not have that much cash sitting in the bank. Much of his net worth is in the form of assets: stocks, real estate, and other investments. If he sold everything that he has and paid any debts, he would theoretically have the $86 Billion. I say "theoretically" because in the amounts of stock that he owns, he could cause a price drop by selling it all at once.
